STOP HINGE.

Application filed March 24, 1922. Serial No. 546,232.

To all whom it may concern:

Be it known that I, STUART W. PARSONS, a citizen of the United States, and a resident of New Britain, county of Hartford, State of Connecticut, have invented certain new and useful Improvements in a Stop Hinge, of which the following is a specification. r

The aim of the present invention is to provide a stop hinge having various features of novelty and advantage, andmore par tioularly to providea hinge of this sort which is ver simple in construction and therefore ma e economically manufactured, and whlch is very sturdy in that it is enabled to resist comparatively great stralns and stresses placed upon it.

In the accompanying drawings, wherein I have shown for illustrative purposes two embodiments which the invention maytake: Fig. 1 is a plan view of one form of my improved hinge; Fig. 2 is an edge view thereof with the leaf (1' partially in longitudinal section, 26, Fig. 3, the detail view in edge elevation with the end of the pintle cut away to show the manner in which the pintle is held against rotation relative to one of the leaves; Fig. 4 is a blank from which the leaf a of the hinge shown in Fig. 1 is formed; Fig. 5 is. the-pers ective view of a butt hinge, showing anot erembodiment of the invention;

Fig. 6 is a longitudinal, sectional view through the hinge shown in Fig. 5; and

Fig. 7'is a detail view taken substantially on line 7-7 of Fig. 5.

' Referring to the drawings in detail, and more particularly to that embodiment shown in Figures 1-4, a and 6 denote the respective leaves and o designates the pintle pivotally connecting the leaves together. Each of theleaves is preferably constructed of sheet metal by stamping out a blank to the .desired configuration and then drawing or pressing the blank to the required form. The leaf b has a knuckle 10 formed integral therewith by rolling the metal upon itself. This knuckle; in the embodiment shown in Figures 1 1, preferably rises above the plane of the body portion of the leaf 6. The leaf 6' is provided with the longitudinally. extend- .also serves to strengthen the knuckle 10, anchoring and bracing it, as it were, against distortion and bending, and particularly at its juncture with the body portion of the leaf.

One end of the leaf a i upturned, thus providing a wall 15, which is upset or inclined to the plane of the leaf a. This wall forms a socket, so to speak, for the reception of the knuckle 10 of the leaf 6. At each end of the wall or flange 15 and formed integral therewith is an apertured projection 16., these projections being bent down at right angles to the leaf a so as to constitute theknuckles or bearings between which the knuckle 10 is interposed. The pintle 0 is positioned :and suitably secured in the aligned apertures or openings in the knuckles. The leaf 0 is provided with a longitudinally extending, reinforcing rib 18, similar to the rib 12 of leaf 6. This rib 18, at its inner end, merges into and is integral with the inclined wall 15. The edge of the wall 15 may be recessed as at 20 and the edge -of this recess constitutes a shoulder or abutment which is adapted to engage, as shown by dotted lines of Fig. 2, against the rib 12 of the leaf I), and thus limit the extent to which the leaves may be swung relative to one another. It will be seen that .since the projections or-knuckles 16 are at right angles to the plane of the leaf a and to the length of the pintle c the strains on these knuckles are in the direction of their planes. These knuckles are integral with the wall 15 of ithe leaf a, and'this wall is strengthened,

4 v and therefore a very substantial bearing in ',tation in suitable manner relative to the knuckles 16 while the leaf 6 is adapted to swing relative to the pintle. To this end the pintle opening 21 in one of the knuckles 16 i non-circular, and that portion. of the pintle positioned in this opening is of sim-' ilar cross-section, thus preventing rotation between knuckles 16 and the pintle. In the present instance, the wall of the opening 21 in the knuckle 16 is notched, as at 22,-. and the pintle is expanded into this notch, so that the pintle and knuckle are in interlocked engagement.

Reference may now be had to Figures 5-7, wherein I have shown my invention incorporated in a butt-hinge. In this embod' ment, the leaf 6', which is preferably constructed of sheet metal, has a knuckle 10, formed by rolling the end of the leaf back upon itself. The leaf a, which is also formed by stamping out a blank'and pressing the blank to the desired shape, has an upturned end wall 15 providing an abutment 20 raised above the plane of the leafa'. The end wall or flange .15 forms a socket for the knuckle 10', and the ends of this socket are closed by webs or projections 16, constituting knuckles for the pintle 0. 16f are integral with the body-portion of the leaf (1' and the end wall 15 thereof.

' One of the knuckles 16 is provided with a square opening 30, snugly fitting in the opening 21' so as to prevent the pintle from turning in the knuckles 16. As in the preceding embodiment, the leaf b hasa comparatively long and therefore substantial bearing on the pintle, and thus there is little or,no wear between the parts. With the arrangement describedyit will be seen that the abutment 20 forms a stop against which the leaf 6 is brought-when the hinged member is thrown open. Owing to the fact that the knuckles or webs 16' are integral with the body portion of the leaf a andthe end wall 15', these webs, though being comparatively thin, have extreme strength; and, furthermore, these webs strengthen and serve to hold the end wall 15' against bending.

It is of course obvious that the invention is susceptible of various modifications and changes which are within the spirit of the invention without departing from the scope of the following, claims, it bein understood that the present disclosure of the invention is by way of illustration only and it is not to be taken as, restrictive of my conception.

I claim as my invention:

1. A stop hinge comprising a pair of leaves constructed of sheet metal, one of It will be seen that the Webs or knuckles said'leaves having a wall at one end curved to form a socket, and side portions integral with the side ed es of said wall and at right angles thereto, t e" other leaf having a continuous, unbroken knuckle positioned within said socket and. extending substantially. the

knuckle, the end edge of said wall constitoting an abutment against which the other leaf is adapted to engage, side portions closing the ends of said socket and, receiving said knuckle therebetween, and a pintle supported by said side portions and held against rotation relative thereto and extending through said relatively long knuckle.

3. A stop butt hinge comprising a pair of leaves constructed of sheet metal, one of said leaves having an end wall curved outwardly and backwardly of the'body portion of the leaf and constituting a socket having integral side portions at right angles to the plane of the leaf, and a pintle supported by said side portions and held against rotation relative thereto, the other of said leaves having a continuous, unbroken knuckle positioned within and concealed by said socket and extending substantially the entire distance between the side portions and engaging and rotatable on said pintle.

4. A stop butt hinge comprising a pair of leaves constructed of sheet metal and adapted to close one on the other, .one of said leaves having one end curved backwardly of its body portion to provide an end wall constituting a socket having integral side portions disposed at right angles to the plane of the leaf, the other, of said leaves having one end rolled back upon itself in the same direction as said end wall and constituting a continuous, unbroken knuckle, said knuckle being positioned within and concealed by said socket and extending substantially the entire distance between said side portions, and a pintle extending through said sideportions and said knuckle,

one of said side portions havin a noncircular opening, and said pintle iaving a non-circular portion engaging in said opening whereby relative rotation betweeii saidpintle and said knuckle is prevented? 5. A hinge comprising a pair of leaves constructed of sheet metal, one of said leaves having integral bent-up side portions disposed at right angles to said leaf and constituting relatively thin knuckles, and a pintle supported by said side portions, the other of said leaves having a continuous, unbroken knuckle positioned and extending substantially the entire distance between said side portions and having a long bearing on said pintle, one of said side portions having a non-circular aperture and said pintle having anon-circular portion engag ing in said aperture whereby relative rota- 10 tion between said pintle and said side por tions is prevented.
